A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring , a raised weight , or a compressed gas .
A diaphragm type pressurizer on a domestic rainwater system, with the pump and Square D pressure switch in the background. A pressure tank or pressurizer is a type of hydraulic accumulator used in a piping system to maintain a desired pressure. Applications include buffering water pressure in homes. [1]
A capacitor is equivalent to a tank with one connection at each end and a rubber sheet dividing the tank in two lengthwise [7] (a hydraulic accumulator). When water is forced into one pipe, equal water is simultaneously forced out of the other pipe, yet no water can penetrate the rubber diaphragm. Energy is stored by the stretching of the rubber.
In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure , or as a device that vibrates when certain frequencies are applied to it.
I see that a spring type hydraulic accumulator is mentioned. I wonder whether this type of accumulator was ever used. Anyway, I do not know one application. Reason is that the amount of energy that can be stored in a spring driven hydraulic accumulator is negligible. So it is better to delete this item. Jeff 11:46, 25 March 2007 (UTC)
